Application filed April 24,

To all whom it may concern:

Be 1t known thatlgdonx H. RIGBY, a hoe at Ber erly, in the countyofIEsseX and iState of Massachusetts,have iniented. certain 'Im'provementsin Sole-Edge-Finishing .Ma chines, of which the followingdescription, in connection with the accompanying draw ings, is aspecificatiom-like reference characin the several figures.

ters on the drawings indicating like parts This invention relates toedge setting machines of that type in which an iron for sett ing thesole edge is vibrated backwardlv and forwardly along the length of thesole edge, and in whichan'indenting wheel mounted adjacentto the edgesettingiron in positionto operate upon the upper surface of the welt orsimilar substauceor sole;

Heretot'ore it has heenproposed to mount the indenting wheel in. variousways so that- .it might move relatively to the edge setting iron,against the action of a spring, to adapt the wheel for indentillilffwelts 'or sole margins of different widths None of these structures hasenabled anyprovisionto be made for conveniently adjusting the wheel.

' toward and from the surface tobe'. operated upon so as to readilyaccommodate solesiot' hfi ETQnt thickness.

An important feature of the present 'invention consists in provision forrelative vertical adjustment ot'ed e iron and indenting Another featureof the ,inventio 'i com,

prises. a bodily movable indenting wheel which can be manually swungaside from its normal position to facilitate the-ren'ioval 'oi'i oneiron and t-he substitution of another iron for it. p

In the illustrated embodiment oi. the 'iuvention, the indenting wheel isso mounted that it will follow the eontour ot the upper backed by itslast. irrespective of the con- 5 tour of the sole,'wliil'e being carriedby a ier type of machine;

swinging support ivhiclrcan be readily manually adjusted to permit themachineto be used ,tor, operating upon soles otvarying thicknesses.

It has been. proposed to ,n'ioiuitganzedge setting iron forpermissive:movement about l ahorizontal axis in order'to. m st theitool thevertical caused, [for example, by careless dent-ing .wheel so that suchmovement ot the iron does not vary the distancerelation heto follow asole edge or varying relation to;

edge trimming. v The present invention pro-f v1d es.an independent mountng for the n tween the indenting wheeland thesole edge.

To facilitatethe employment of an; edge finishing machine for .(l1if6lf8nt grades; or

kinds of work, it eustomaryt nount the sett ng tool or iron so'thatiltranbe replaced invention is to enable the change to be madequickly. In the machine illustratedto ex emplifythe inventlon, the vtoolorsiron s so mounted that althoughit is-held securely in operative positon, it can bee ected trom its holder bya manual. operation, suchejection being", preferably preceded by a displacemen-t of the indentingwheel. r j @Other features 'of my. invention will beeome apparentasrhereinafter described. In the acermipanying:drawings, theinventionisillustrated-in. connection with a 1 machinenof the typedescribed inUnited States LettersPa-tent No. LOTSfiSAigranterl Nov. 18,1913; but" it is to ,be understood that I do not limit myself to the useof my .im-

provements inv connection with I that p articu- In the drawings Fig. 1is a side elevation of a. portion of a maehine of the type illustratedin the pate-nt 7 above rete-rerdto, said machine being equ-ipped. withLmv improved edge setting and indenting devices; t Fig. 2 is a sideelevation of the devices which include my present improvements.

Figs, 3 and tareperspeetiveview I speetively illustrating thetool holderand the time to be assembled.

When my;imin'ovementsare embodied in amachine of the 'tvpe'indicatedjinFigi'l.

the workto be operated upon is clamped n a jack or work support 12{Fig 1) carried tool separated from each other but in posi-,

by a vertical post-in a frame member 13 and so mounted that it may haveuniversal movement in a horizontal plane. A block ll. supports the treadface of the shoe sole and a rest 15 supports the tread tace oi? theheel. A U-shaped clamp 16 engages the counter partof the shoe and aclamp 17 is carried by a plunger 18 which is operated by a handle 19pivoted at 20. I

The mounting for the edge setting tool 21 (Figs. 2, 3 and comprises atool holder 2:3 having a shank slidably positioned in a -member which isoscillated in anextension 24 (Fig. 1) from a sleeve 25 that is totatablv mounted in a bearing frame 26 which is connected by pivots 27 totwo pairs oi" 'twin leversQS, 29. One pair of levers 28 is pivoteddirectl upon a lever 30, while the other pair of levers 29 is connectedto the lever 30 through a bell-c ank 31, the latter being connected withthe frame of the machine by an anchor link 32. Bvthis construction, thetool holder can be nuwed laterally toward and tromthe work. For afurther understanding of the motions imparted to the sleeve trameQG andthe parts carried thereby, reference may be had .to the Patent1,078.684. is stated above, however, I do not limit myself to machinesof this particular type, but it to be no derstood that, whatever thetips ot machinc may be, the shank and the holder and all parts carriedtherebv a re vibrated as usual along the. length of the sole edge.

Referring now particularly to Figs. 2, 3 and at which illustrate theparticular features of my i. vention, the bi'ackebshaped holder 22 isformed or provided at its upper end with an ear 33, said brzurlzet-shapedholder being slotted or recessed and the two memaers thereo'f'novided with vertical wavsfiil in which an L-shaped "block is fitted toslide. Risingi'rom the upper portion of the block is a threaded pin. 35.said pin pass ing through the car 33 and jprovidt-id with nuts 37 bymeans of which the block can be raised and lowered in the ways 34. Pivotally connected at 38 to the angle portion of the block is an arm 39 bywhich the stitch indenting wheel 4-0 supported in a swinging manner.said wheel being connected to a carrier ll pivoted at 1-12 to the lowerend of the arm 39. The carrier 41. is .pivotally connected at 43 to thelower endotlever s -l carried by a rockshatt lf) mounted in the'end ofthe lower member of the L-shaped block 35. Thelower arm. of the leverltis by preterence parallel to, and ot the same length as. the arm 39 sothat the carrier can be swung without changing the inclination oi. thewheel axis. The lever ltis integral with or secured to the rockshatt oneend of which projects through a slot in one of the check pieces of theholder T he upper end of the lever it has a slot 46 which receives a pin4:? projecting from the upper end of the lever 48 pivoted zit-49 to theholder 22. The end of the rockshaft which pro ects through the slot 65has secured thereto an arm 50 provided with a-tbumb piece 51 the purposeof which will be hereinafter explained.

T he reason tor the slot and pin connection i i? is to ensure permanentconnection-between the levers i l and 48 throughout all vertical adjustmcnts otthe wheel carrying block 35.

l he lower end of the lever 48 has a for wardly projecting andpreferably rounded tip .Bearing against the back otthe lower end of thelever 1-8 is a sliding pin or plunger 53 which is slotted for a pin 5imounted in the holder and pro ecting it back against the action oilspring transinitted through the lever 48, the lever ll and the memberatl. In this manner the wheel 40 is not only adjustably supported but isalso yieldingly supported so that it may move in and out relatively tothe margin of the shoe sole so as to automatically accmnmodate itself tothe varying widths of the shoe welt or corresponding part. The outerlimit oi. movement or swing of the wheel 10 is detern'iincd by the innerendo't the slotin the pin bearing againstthe limit ng pin lhat is. whenthe spring 55 acts upon the pin 53 so as to swing the lower end of lever48 to the left from the position in'Fig. 2 as tar as the slotin the pinBil-will permit, the intermediate connecting lever 44. will transmitthat an'ioui'it' of movement and no more to the wheel 4-0.

Consequently, when there is no work in place, the wheel :40 cannot beswung sotar out as to be out of position to be swung back again when thework is placed. in position for edge finishing and indenting.

The lever 4-8 also scrvesas a means for ejecting the tool 21tronrposition. Thetool 21 is secured to a block Behaving a heel. or camportion 57. by suitable means such as screw 58. The tool 21 has angularrecesses 59 which engage the fulcrum edges 60 ot' the holder 22 topermit rotation about a horizontal axis to lit the vertical. t'ace oithe sole edge at all times. Said holder provided. on the inner walls ofits cheek pieces, with ledges 61, one of said. ledges being cutaway orrecessed as 62. When the tool 21" and its block 56, as shown in'Fig.4,.are' inserted to position in the'holder 22 (Fig. 3), the block 56 ispassed between the cheek pieces of the'holderbelow the ledges 61 and theupper portion of the tool 21 is pushed in above the ledges 61 until theside-lug 63 of' the tool drops into the recess 62. The parts 7 are soproportioned that at this time the fulcrrun edges of the holder 22 litthe I angular recesses 59'of the tool.

The slot! 6-1 formed in one of the cheek pieces of the holder 22, whichslot is formed when'the ledge 61 is cut away to form the recess 62,enables a tool to be inserted under the lug 63 to lift the latter up ifthe tool should be stuck and it is desired to removeit. Ordinarily,however, the tool is easily ejected in the following manner By pressingagainst the finger piece 51, the shaft 45 is rocked and the lever 44' isswung so as to transmit swinging motion to the arm 39, thereby swingingthe indenting wheel 40 away and up from the position shown in Fig. 2, itbeing assumed. of course, that at this time there is no work in place.The first portion of this movement carries the wheel 40 some littledistance away from the tool 21. During continued actuation of therockshaft arm 50 by means of the thumb piece 51 the lever 48, owing tothe slot and pin connection 46, 47 with the lever 44, is actuated sothat the tip 52 at the lower end of the lever 48 contacts with the camportion 57 of the tool block 56 and lifts therear end thereof up untilthe lug 63 clears the recess 62, and then a slight further movementthrows the tool or iron awayfrom the supporting ledges to enable a newtool to bequickly substituted for the one removed.
